Zeitvariantes Trag- und Schädigungsverhalten von mehrfach wiederholt beanspruchtem polymermodifizierten Beton (PCC), Teil 1: Experimentelle Untersuchungen

Time-variant Behaviour of Polymer Modified Concrete (PCC) under Repeated Stress with Consideration of Damage. Part 1: Experimental Studies

The experimental results of the investigations into polymer-modified concrete with continuously repeated compression or tension load are introduced in the provided work and compared to similar experiments on normal- and high-strength concrete. Special attention is dedicated to the stress-strain relation and the degradation of stiffness as well as the non-linear long-term behaviour and tension-stiffening. Stiffness degradation and nonlinear creep of polymer-modified concrete show that maximum strain situations have to be taken into consideration of the behaviour analysis of concrete structures under long-term loading.
